Unable to click button links inside header bar

Ionic Framework ionic-v3
1

I have created a button to rate my app inside the header. This is my markup:

<ion-header-bar class="bar-dark">
    <h1 class="title title-left">App Title</h1>
    <a class="button rate-me button-light" href="http://my-link.com/here">Rate Me</a>
</ion-header-bar>

Clicking on the link in my Android does nothing. However, I can click the button in the browser and it opens up the webpage correctly. What’s going on here?

Thanks.
